To all whom it may concern:

Be it known that 1, JOHN M. HOWARTH, a citizen of the United States, residing at .Vausau, in the county of Marathon and State of Wisconsin, have invented a new and useful Improvement in Machines and Processes for Pulling Candy, of which the. following is a specification.

My invention relates to an improved device for stretching or pulling certain kinds of candy and consists in the constructions, arrangements and combinations of parts herein described and claimed.

Among the objects of my invention is to provide a machine which shall be capable of pulling certain kinds of candy which require a certain amount of working before reachin a state from which they will readily arden.

Other objects and advantages will appear in the following specification reference being made to the accompanying drawings in which Figure 1 is a perspective View of the device showing the machine as in operation. Fig. 2 is a cross section on the line 22 on Fig. 1. Fig. 3 is a detail cross section on line 33 on Fig. 1. Figs. 4 to 9 inclusive are diagrammatic views illustrating the action on a batch of candy during one complete pulling operation.

in the drawings, 1 represents a bed-plate which is supported by legs 2 which are secured to the bed-plate at each end. Mounted on one end of the bed-plate is a standard 3 which is formed with a bearing boss 4: at the top and bottom as shown, a third bearing boss 5 being located midway of the upper and lower bosses for the support of the oscillator shaft 6.

An oscillator bar 7 is secured to the front end of the shaft 6 and pins 8 and 9 are in turn secured to the opposite ends of the bar 7 from whence they project forwardly and receive and holdthe'candy batch. The bar 7 is oscillated through the medium of a pinion 10 which is secured to the rear end of the shaft 6.

A shaft 11 is located in the lower boss A and is supported near its front end by a bearing 12, a crank 13 being secured to the front end of the shaft 11. An arm 14 is loosely mounted on the shaft 11 just behind the standard 3, the arm having a gear segment 15 at its upper end thegear segment meshing with the pinion l0 and imparting movement to the pinion when the arm 14 is moved. A pitman 16 connects the lower end of the arm 14 with a crank 17 on a driven shaft 18 which is mounted in depending bearings 19 at the opposite end of the bed-plate 1, as shown in Figs. 1 and 3. A drive shaft 20 is mounted above the shaft 18 in other bearings on the bed-plate 1 and an operating crank 21 is removably attached to the end of the shaft 20 so that it may be turned to operate the device. While I have illustrated a crank for manually operating the machine, it will be understood that in practice a motor will be connected with the shaft 20.

A pinion 22 on the drive shaft 20 meshes with a gear 23 on the driven shaft 18. A crank 2% is also mounted on the front end of the driven shaft 18 and a pitman 25 is connected to the ends of the crank 24: on the shaft 18 and 13 on the shaft 11 so that an oscillatory or pendulous motion is imparted to the shaft 11 as the shaft 18 rotates. An arm 26 is secured to the shaft 11 close to the bearing 12 and a pin 27 projects inwardly from the upper end of the arm 26 on which the pin is mounted.

A shaft 28 is located in the top bearing boss 4 as shown in Fig. 2, a crank 29 being secured to the rear end of the shaft. A connecting rod 30 joins the crank 29 with a similar crank 31 on the shaft 11 so that the pendulous motion of the shaft 11 will be imparted to the shaft 28. The shaft 28 eX- tends forwardly and bends downwardly then inwardly to form a finger or pin 32 similar to 27. i

The shafts 11 and 28, their pins 27 and 32 and the cranks 31 and 29 are virtually bellcranks which are placed in such positions on the standard 3 that the pins 27 and 32 will occupy opposite positions at each side of the standard when the bell cranks are at the limits of their movements. The connection 30 causes the bell-cranks to move together but since the pins of the bell cranks are positioned oppositely of the center of the standard 3, the pins will be caused to move in opposite directions. At the same time the pins 8 and 9 on the bar 7 are performing a part of their oscillatory strokes and the result is a stretching of the candy imposed on the pins.

Having thus described the mechanism of the device, the operation thereof is as follows:-Let it be assumed that a batch of candy has been placed in position on the pins 8 and 9 of the oscillating bar 7. This is done when bar 7 is substantially horizontal as in Fig. 5, the pins 27 and 32 being out of the way at such a time. The first four steps will be as shown in Figs. 6, 7, 8, and 9 and during this part of the operation the pins 32 and 27 will have crossed the path of the pins 8 and 9 and taken up the candy batch. The next position would be as in Fig. 4 from which the description of the pulling process, will commence. At this time the candy forms a reversed letter Z as shown in Fig. 4, from which it will be observed, the bar 7 is at one limit of its movement and just about to move as indicated by the arrow. The pins 32 and 27 haveyet a small distance to travel causing the candy to be stretched still farther. I Vhen the bellcrank pins 32 and 27 reach the limits of their movements as in Fig. 5, the oscillating pins 8 and 9 will have moved ,to such a position as to bring the candy batch together.

The bell-cranks now reverse and start in opposite directions which are the same directions as those of the pins 8 and 9 as shown in Fig. 6. l/Vhen this position is reached the pins 32 and 27 will fold the outer portions of the batch under the pins 8 and 9 these pins now being near the place of reversal which is shown in Fig. 7. As the pins 8 and 9 start back the pins. 32 and 27 still continue their movement since they have not completed their outward travel and thus the second stretching process commences. Since the pins 8 and 9 new travel away from the pins 32 and 27 as in Fig. 8 the candy will be pulled into the shape of a letter Z and when the pins 8 and 9 reach their first positions the candy batch will be brought together again as in Fig. 9. The pulling process is now repeated but the parts will move in opposite directions from those mentioned in the foregoing description.

The co-acting pins 8 and 32 and 9 and 27 each describe a numeral 8 in the movements just described and I have found that by fastening a cord to one pin and extending the long end over the other, then making a one-half revolution of the bar 7 that twentythree inches of string are used.

While the structure shown embodies preferred constructions, obviously variations and modifications may be made without departing from the spirit of the invention or the scope of the claims.
